Unable to send message on same connection from two different processes in contiki

[subhanshus-optimus]

I have created two processes in Contiki.
In the first process, I have created a UDP connection and send a test message from the same and this message got successfully received at the other end.
In the second process I just try send the same message, but it is not received on another end.

I have made it is static so that it can be used in both processes. static struct uip_udp_conn *conn

I guess this issue is occurring since contents of connection are destroyed in second process.
How I can resolve this issue?
